(4)The 2-OLS interface module (=IFM) is an Optical Low Speed Serial interface module which can be used to transport low speed serial data and E1 data. This IFM has four ports: two Optical Serial ports (=port1, port2) and two E1 ports (=port3, port4). This IFM can be used in 3 different service types (a mix in one IFM is possible): Local Mode, Circuit Emulation Optical Serial Data and Circuit Emulation E1 Data.
